Abstract
- We report the experimental investigations of two-phase flow boiling heat transfer characteristics of a refrigerant in a microfluidic channel at a high mass flux (more than 1000 kg/m<superscript>2</superscript> s). We investigate the heat transfer coefficients at a heat flux range of 7.63 kW/m<superscript>2</superscript>ā49.46 kW/m<superscript>2</superscript>, mass flux range of 600 kg/m<superscript>2</superscript> sā1400 kg/m<superscript>2</superscript> s (high mass flux), and saturation temperature range of 23 °Cā31 °C. We propose the new two-phase flow boiling heat transfer correlation of a refrigerant, which is used as the working fluid for the present experiments, at the microfluidic scale. We experimentally establish the functional relationship of two-phase flow boiling heat transfer correlation of the refrigerant during flow boiling in a rectangular microchannel with the Reynolds number, the boiling number, and the Weber number. We believe that the inferences of this study may provide a design basis for the micro-heat exchanger, typically used for thermal management in electronic devices, micro-electro-mechanical systems, and electric vehicle battery cooling system.
